I have it in an '02 Super T and '04 Z150FR SL. I've run it in that Super T through at least 3 oil changes with the original seals and no problems at all. I'm guessing that pic you posted is a sample pic because 10wt. is pretty heavy for most Zoke applications. I know some use it, but 7.5wt is most commonly used and I usually even go down to 5wt.opticals said:anyone tried PJ1 fork oil on their marzocchi fork?
